www.DataSheet4U.com TECHNICAL DATA PCM CODEC - FILTER KK145567 KK145567N is a one-chip PCM-cofidec which converts speech signal into digital form and backwards. The IC is design to operate in synchronous and asynchronous systems and is comprised of: - reference generator; - filters on switching capacitors in transmission and receipt channels ; - two operational amplifiers. The IC does signal companding under the A-low and full differential processing of analogue signals for reduction of noises. Typical dissipated power is 40mW, under reduced power – 1 mW at ±5 V.
